Hydrostick Aquastop (AquaBarrier) DV-320/20 (PVC) – deformation inner screw made of polyvinyl chloride, used for sealing expansion joints in the construction of buried and underground structures, 320 (mm) – total width of the waterproofing key, 20 (mm) , filled with expanded polystyrene.

The waterstop DV 320/20 is made of PVC, which makes it possible to provide a more durable weld that withstands greater water pressure and provides rigidity of the structure, but reduces the temperature range of application.

Mounting of waterproofing keys made on the basis of PVC is carried out with the help of special equipment, either “Tops for welding water-sticks”, or a conventional hand-held hot air device, used, as a rule, for welding PVC membranes.
